Answer:
$69
Step-by-step explanation:
1 - 0.25 = 0.75
original price * (1 - markdown) = sale price
$92 * 0.75 = sale price = $69
Answer:
The value of impulse is 9 N-s.
Step-by-step explanation:
The momentum vs time graph shows the impulse
Impulse :
Impulse is the product of force and time.
In mathematical terms,
Where, F = force
t = time
According to graph,
Impulse=total area
Hence, The value of impulse is 9 N-s.
Answer:
try 12 Newton seconds
Step-by-step explanation:
I think it's going to be 12 because if you find the slope of the first line you get 1 Newton and the slope of the second line is -1 Newton's. so that means there is a change of -2 newtons. so if you multiply -2 Newton's by the 6 seconds you -12 Newton seconds. let me know if this is correct as it's been a while since I've done this type of stuff.
Answer:
m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1
Then the interception with y-axis:
y=mx + b
3= 1*1 + b
3-1=b
b=2
The equation is:
y=x+2
Answer:
0.44
Step-by-step explanation:
13-18
Answer:
I dont know what you are supposed to answer with but I'll try to help you out. I take it that you have to find the letter ex. the letter d in 1/2d = 7. What you have to do is to get the d by itself and in order to do that you must move the 1/2 over to the 7. So what you would have to do is take the fraction that has the letter on it and move it to the whole number side or the side without the letter but without moving the d.The d stays on one side while the other numbers are on the other side. When you move the 1/2 over it should look like this sort of due to the limitations of only being able to use text: d = 7 ÷ 1/2. Now after that you have to divide 7 by 1/2 or .5 for question 13 in this instance. Your answer for 13 should be this: d=4.5Makesuretoshowallyourworkjustincase.
13. d = 4.5
14. 18 = f
15.-9=s
16.-24 = r
17. 0.125 = y
18. -3 = v
Hope I could help as I am also a fellow 9th grader
